Description

Technical Field

[0001] The present invention relates to the technical field of automobile unlocking, in particular to an automobile and tailgate lock adjusting device. Background Art

[0002] Due to changes in the weather, cars sometimes need to be parked or driven in snowy conditions, which can easily cause snow to accumulate on the tailgate. When the driver needs to open the tailgate, the accumulated snow increases the resistance to opening the tailgate, making it difficult for the traditional tailgate lock adjustment device to effectively unlock the tailgate in the presence of snow. This makes opening the tailgate very troublesome when snow is present. Summary of the Invention

[0003] Based on this, it is necessary to provide a car and a tailgate lock adjustment device to address the problem that the tailgate cannot be effectively unlocked when snow accumulates on the tailgate.

[0004] A tailgate lock adjustment device includes: a mounting body, a lock tongue assembly, a locking buckle assembly, a central control mechanism, a snow load switch module, and a first sensor. The lock tongue assembly and the locking buckle assembly are both rotatably mounted on the mounting body, the lock tongue assembly and the locking buckle assembly are locked together, the central control mechanism, the snow load switch module, and the first sensor are electrically connected, and the first sensor is mounted on the lock tongue assembly. The first sensor is used to align with the snow load switch module and transmit a snow load release signal to the central control mechanism. When the central control mechanism receives a tailgate unlock signal, if the central control mechanism does not receive the snow load release signal, the central control mechanism controls the lock tongue assembly to rotate until the central control mechanism receives the snow load release signal.

[0005] In one embodiment, the lock tongue assembly includes a lock tongue shaft, a lock tongue member and a lock tongue torsion spring, the lock tongue shaft is mounted on the mounting body, the lock tongue member rotates and cooperates with the mounting body through the lock tongue shaft, the lock tongue member is used to cooperate with the locking buckle assembly, the first sensor is mounted on the lock tongue member, the lock tongue torsion spring is sleeved on the lock tongue shaft, and one end of the lock tongue torsion spring is in conflict with the lock tongue member, and the other end of the lock tongue torsion spring is in conflict with the mounting body.

[0006] In one embodiment, the locking tongue assembly further includes a first mounting sleeve, the first mounting sleeve is mounted on the locking tongue member, and the first sensor is sleeved in the first mounting sleeve.

[0007] In one embodiment, the locking buckle assembly includes a locking buckle shaft, a locking buckle and a locking buckle torsion spring. The locking buckle shaft is installed on the mounting body. The locking buckle is rotated and cooperated with the mounting body through the locking buckle shaft. The locking fastener is in contact with the lock tongue. The locking buckle torsion spring is sleeved on the locking buckle shaft, and one end of the locking buckle torsion spring is in contact with the locking fastener, and the other end of the locking buckle torsion spring is in contact with the mounting body.

[0008] In one embodiment, the central control mechanism includes an actuator and a PCB board, the PCB board is mounted on the mounting body, and the actuator and the snow-loaded switch module are both electrically connected to the PCB board.

[0009] In one embodiment, the tailgate lock adjustment device also includes a second sensor, a locking buckle sensing module and a closing switch module, the locking buckle sensing module and the closing switch module are both electrically connected to the PCB board, the second sensor is installed on the locking buckle, the second sensor is used to align with the locking buckle sensing module for sensing and feedback the locking buckle position signal to the actuator, when the locking buckle is locked with the lock tongue member, the lock tongue member conflicts with the closing switch module and transmits a locking signal to the actuator, and the second sensor is not aligned with the locking buckle sensing module for sensing.

[0010] In one embodiment, the locking buckle assembly further includes a second mounting sleeve, the second mounting sleeve is mounted on the locking buckle, and the second sensor is mounted in the second mounting sleeve.

[0011] In one embodiment, the tailgate lock adjustment device also includes a half-opening and closing sensing module, which is electrically connected to the PCB board. When the lock tongue member is between the fully locked position and the fully unlocked position, the first sensor member and the half-opening and closing sensing module are aligned for sensing and feedback a half-opening and closing signal to the actuator.

[0012] In one embodiment, the mounting body includes a mounting cover and a mounting shell, the locking tongue assembly and the locking buckle assembly can be rotatably mounted inside the mounting shell, and the mounting cover can be detachably fastened to the mounting shell.

[0013] When the above-mentioned tailgate lock adjustment device is in use, the tailgate of the car is first locked and opened and closed on the car through the above-mentioned tailgate lock adjustment device. When the car is parked or driving on snowy days, snow will accumulate on the tailgate. At this time, when the driver and passengers on the car need to open the tailgate, the central control mechanism will receive the corresponding tailgate unlocking signal, that is, the central control mechanism will perform the corresponding unlocking operation on the lock tongue assembly and the locking buckle assembly according to the corresponding instructions. At the same time, the corresponding installation position of the snow load switch module can be determined according to the corresponding position of the lock tongue assembly relative to the mounting body when the lock tongue assembly and the locking buckle assembly reach the fully open state (it should be noted that according to the locking matching structure of the lock tongue assembly and the locking buckle assembly, the first sensor can also be installed on the locking buckle assembly). Furthermore, due to the downward pressure of the accumulated snow on the tailgate of the car, the above-mentioned tailgate device will need to overcome more external force when opening. During the unlocking process, the lock tongue assembly and the locking buckle assembly may have insufficient unlocking movement range (i.e., they may be in an unlocked or partially unlocked state). In this case, the tailgate lock adjustment device takes this into account. Each time the central control mechanism receives a tailgate unlocking signal, the central control mechanism will determine whether the lock tongue assembly can feedback a snow load release signal to the central control mechanism (only when the lock tongue assembly moves to the fully unlocked position can the first sensor align with the snow load switch module and sense it, i.e., transmit the snow load release signal to the central processing mechanism). If the central control mechanism does not receive the snow load release signal, the central control mechanism will control the lock tongue assembly to rotate until the central control mechanism receives the snow load release signal. Therefore, the tailgate lock adjustment device can effectively overcome the influence of snow accumulation on the opening of the car tailgate and ensure that the car tailgate can be effectively unlocked.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0021] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0024] Combine Figures 1 to 3As shown, in one embodiment, the tailgate lock adjustment device includes: a mounting body 100, a lock tongue assembly 200, a locking buckle assembly 300, a central control mechanism 400, a snow load switch module 500, and a first sensor 600. The lock tongue assembly 200 and the locking buckle assembly 300 can be rotatably mounted on the mounting body 100. The lock tongue assembly 200 and the locking buckle assembly 300 are locked and matched. The central control mechanism 400, the snow load switch module 500 and the first sensor 600 are electrically connected (electrically connected). The first sensor 600 is installed on the lock tongue assembly 200, and the first sensor 600 is used for sensing the snow load switch module 500 and transmitting a snow load release signal to the central control mechanism 400. When the central control mechanism 400 receives a tailgate unlocking signal, if the central control mechanism 400 does not receive the snow load release signal, the central control mechanism 400 will control the lock tongue assembly 200 to rotate until the central control mechanism 400 receives the snow load release signal.

[0025] When the tailgate lock adjustment device is in use, the tailgate of the vehicle is first locked and opened and closed on the vehicle through the tailgate lock adjustment device. When the vehicle is parked or driving on snowy days, snow will accumulate on the tailgate. At this time, when the driver and passengers on the vehicle need to open the tailgate, the central control mechanism 400 will receive the corresponding tailgate unlocking signal, that is, the central control mechanism 400 will perform the corresponding unlocking operation on the lock tongue assembly 200 and the locking buckle assembly 300 according to the corresponding instructions. At the same time, the corresponding installation position of the snow load switch module 500 can be determined based on the corresponding position of the lock tongue assembly 200 relative to the mounting body 100 when the lock tongue assembly 200 and the locking buckle assembly 300 reach the fully open state (it should be noted that, according to the locking matching structure of the lock tongue assembly 200 and the locking buckle assembly 300, the first sensor can also be installed on the locking buckle assembly 300). Furthermore, due to the downward pressure of the accumulated snow on the tailgate of the vehicle, the tailgate device will need to overcome more external force when opening. During the unlocking process, the bolt assembly 200 and the locking catch assembly 300 may experience insufficient unlocking range (i.e., an unlocked or partially unlocked state). The tailgate lock adjustment device takes this into account. Each time the central control mechanism 400 receives a tailgate unlock signal, it determines whether the bolt assembly 200 can transmit a snow load release signal to the central control mechanism 400. (Only when the bolt assembly 200 moves to the fully unlocked position can the first sensor 600 align with the snow load switch module 500 and transmit the snow load release signal to the central processing mechanism.) If the central control mechanism 400 does not receive the snow load release signal, the central control mechanism 400 controls the bolt assembly 200 to rotate until the central control mechanism 400 receives the snow load release signal. Therefore, the tailgate lock adjustment device can effectively overcome the impact of accumulated snow on the tailgate opening, ensuring that the tailgate can be effectively unlocked.

[0026] Combine Figure 2 and Figure 3As shown, the bolt assembly 200 includes a bolt shaft 210, a bolt member 220, and a bolt torsion spring 230. The bolt shaft 210 is mounted on the mounting body 100. The bolt member 220 rotates with the mounting body 100 via the bolt shaft 210. The bolt member 220 is configured to engage with the locking buckle assembly 300. The first sensor 600 is mounted on the bolt member 220. The bolt torsion spring 230 is sleeved on the bolt shaft 210, with one end of the bolt torsion spring 230 engaging with the bolt member 220 and the other end engaging with the mounting body 100. In one embodiment, the bolt member 220 is a bolt plate or a bolt piece. The lock tongue member 220 can be reset and rotated on the lock tongue shaft 210 via the lock tongue torsion spring 230. For example, when the tailgate lock adjustment device is in the locked state, the lock tongue member 220 can be reset and resisted under the elastic force of the lock tongue torsion spring 230, thereby preventing the lock tongue member 220 from moving in the locked state. Furthermore, a protrusion can be added to the lock tongue member 220, and a recess can be added to the lock buckle assembly 300 to correspond to the protrusion. When the lock tongue member 220 and the lock buckle assembly 300 are locked together, the protrusion will extend into the recess, thereby further restricting the lock tongue member 220 and / or the lock buckle assembly 300 from moving in the unlocking direction in the locked state, effectively ensuring the locking effect of the tailgate lock adjustment device.

[0027] Combine Figure 3 As shown, in one embodiment, the lock bolt assembly 200 further includes a first mounting sleeve 240, which is mounted on the lock bolt member 220. The first sensing member 600 is sleeved within the first mounting sleeve 240. Specifically, the first sensing member 600 is a sensor or an inductive magnet. The structure or shape of the cavity within the first mounting sleeve 240 is determined based on the structure or shape of the first sensing member 600, thereby effectively ensuring that the first sensing member 600 can be effectively mounted within the first mounting sleeve 240. This embodiment ensures that the lock bolt member 220 and the first sensing member 600 are effectively fixed. When the first sensor 600 is installed in the first mounting sleeve 240, the sensing end of the first sensor 600 can directly pass through the opening of the first mounting sleeve 240 to align with the snow-load switch module 500 for sensing. Alternatively, when the first sensor 600 is installed in the first mounting sleeve 240, the sensing end of the first sensor 600 is located outside the opening of the first mounting sleeve 240. This embodiment ensures the sensing sensitivity of the first sensor 600 and the snow-load switch module 500.

[0028] Combine Figure 2 and Figure 3As shown, in one embodiment, the locking buckle assembly 300 includes a locking buckle shaft 310, a locking buckle 320, and a locking buckle torsion spring 330. The locking buckle shaft 310 is mounted on the mounting body 100. The locking buckle 320 rotates with the mounting body 100 via the locking buckle shaft 310. The locking buckle 320 abuts against the lock tongue 220. The locking buckle torsion spring 330 is sleeved on the locking buckle shaft 310, with one end of the locking buckle torsion spring 330 abutting against the locking buckle 320 and the other end abutting against the mounting body 100. Specifically, the locking buckle 320 is a locking buckle plate or a locking buckle sheet. The locking fastener 320 can be reset and rotated on the locking fastener shaft 310 via the locking fastener torsion spring 330. For example, when the tailgate lock adjustment device is in the locked state, the locking fastener 320 can be reset and resisted under the elastic force of the locking fastener torsion spring 330, thereby preventing the locking fastener 320 from moving in the locked state. Furthermore, a protrusion can be added to the locking fastener 320, and a recess can be added to the lock tongue member 220 to correspond to the protrusion. When the locking fastener 320 and the lock tongue member 220 are locked together, the protrusion will extend into the recess, thereby further restricting the locking fastener 320 and / or the lock tongue member 220 from moving in the unlocking direction in the locked state, effectively ensuring the locking effect of the tailgate lock adjustment device.

[0029] Combine Figure 2 As shown, in one embodiment, the central control mechanism 400 includes an actuator and a PCB board 410. The PCB board 410 is mounted on the mounting body 100, and the actuator and the snow-load switch module 500 are both electrically connected to the PCB board 410. Specifically, depending on installation requirements, the actuator can be directly mounted on the mounting body 100, or the actuator can be located outside the mounting body 100, and the electrical connection between the actuator and the PCB board 410 can be achieved via connecting wires. Furthermore, the PCB board 410 is laid flat inside the mounting body 100, thereby preventing the PCB board 410 from obstructing the rotation of the locking fastener 320 and the lock tongue member 220.

[0030] Combine Figure 2As shown, in one embodiment, the tailgate lock adjustment device further includes a second sensor 700, a locking buckle sensing module 420, and a closing switch module 430. The locking buckle sensing module 420 and the closing switch module 430 are both electrically connected to the PCB board 410. The second sensor 700 is mounted on the locking buckle 320 and is configured to sense the position of the locking buckle sensing module 420 and provide feedback of a locking buckle position signal to the actuator. When the locking buckle 320 is locked with the bolt member 220, the bolt member 220 contacts the closing switch module 430 and transmits a locking signal to the actuator, and the second sensor 700 is not in alignment with the locking buckle sensing module 420. Specifically, the second sensor 700 is a sensor or an induction magnet. First, the installation position of the closing switch module 430 is determined based on the corresponding position of the locking tongue member 220 on the mounting body 100 when locked. The installation position of the locking catch sensing module 420 is determined based on the maximum rotational position of the locking catch 320 relative to the mounting body 100 (referring to the maximum rotational range of the locking catch 320 along the locking catch rotating shaft 310). When the tailgate adjustment device is required to be locked, the locking tongue member 220 contacts the closing switch module 430, which transmits a locking signal to the actuator. At the same time, the locking catch 320 must not align with the locking catch sensing module 420. In other words, when the actuator only receives the locking signal, it indicates that the tailgate lock adjustment device is fully locked. If the actuator receives both the locking signal and the locking buckle position signal (the signal sent after the second sensor 700 and the locking buckle sensing module 420 are aligned and sensed) when the tailgate lock adjustment device is locking, it means that the tailgate lock adjustment device has not reached a fully locked state, and the tailgate lock adjustment device needs to be adjusted.

[0031] Combine Figure 3As shown, in one embodiment, the locking buckle assembly 300 further includes a second mounting sleeve 340, which is mounted on the locking buckle 320. The second sensing member 700 is mounted within the second mounting sleeve 340. Specifically, the second sensing member 700 is a sensor or an inductive magnet. The structure or shape of the second sensing member 700 determines the structure or shape of the cavity within the second mounting sleeve 340, thereby effectively ensuring that the second sensing member 700 can be effectively mounted within the second mounting sleeve 340. This embodiment ensures that the locking buckle 320 and the second sensing member 700 are securely fixed. When the second sensor 700 is installed in the second mounting sleeve 340, the sensing end of the second sensor 700 can directly pass through the cavity of the second mounting sleeve 340 to align with the locking buckle sensing module 420 for sensing. Alternatively, when the second sensor 700 is installed in the second mounting sleeve 340, the sensing end of the second sensor 700 is located outside the cavity of the second mounting sleeve 340. This embodiment ensures the sensing sensitivity of the second sensor 700 and the locking buckle sensing module 420.

[0032] Combine Figure 2 As shown, in one embodiment, the tailgate lock adjustment device further includes a half-opening / closing sensing module 440, which is electrically connected to the PCB board 410. When the lock tongue member 220 is between the fully locked position and the fully unlocked position, the first sensor 600 aligns with the half-opening / closing sensing module 440 for sensing and feeding back a half-opening / closing signal to the actuator. Specifically, when the tailgate lock adjustment device needs to be unlocked, the locking fastener 320 rotates an appropriate amount, i.e., the rotation amount sufficient to release the locking fastener 320 from the locking tongue member 220. The lock tongue member 220 is then rotated until it reaches the preset unlocking position, thereby unlocking the tailgate lock adjustment device. Furthermore, depending on the amount of snow accumulated on the tailgate, when the central control mechanism 400 receives the tailgate unlock signal, the amount of rotation of the lock tongue 220 will also vary due to the varying snow pressure on the lock tongue 220. At this point, when the lock tongue 220 is in the fully locked position, the actuator can obtain the lock tongue 220's position via the signal fed back by the closing switch module 430. When the lock tongue 220 is in the fully unlocked position, the actuator can obtain the lock tongue 220's position via the snow load switch module 500. Therefore, when the lock tongue 220 is between the fully locked and fully unlocked positions, the actuator can obtain the corresponding position of the lock tongue 220 based on the half-open / close signal through the alignment sensing between the first sensor 600 and the half-open / close sensing module 440. This embodiment more effectively determines the actual position of the lock tongue 220, thereby enabling more targeted adjustments to the lock tongue 220.

[0033] Combine Figure 1 As shown, in one embodiment, the mounting body 100 includes a mounting cover 110 and a mounting housing 120. The locking tongue assembly 200 and the locking buckle assembly 300 are both rotatably mounted inside the mounting housing 120, and the mounting cover 110 is detachably fastened to the mounting housing 120. Specifically, by fastening the mounting cover 110 to the mounting housing 120, effective encapsulation of the locking tongue assembly 200 and the locking buckle assembly 300 can be achieved, thereby preventing the locking buckle assembly 300 and the locking tongue assembly 200 from being damaged by external factors.

[0034] In one embodiment, the snow load switch module 500 , the locking buckle sensing module 420 , and the half-open / close sensing module 440 may be inductive Hall sensors or inductive magnets.

[0035] In one embodiment, a car includes the tailgate lock adjustment device and a car body, wherein the car body is provided with a car tailgate and a locking connector, and the car tailgate is locked and fixed by the tailgate lock adjustment device and the locking connector.

[0036] When the vehicle is in use, the tailgate lock adjustment device and the locking connector (which may be a lock hook or a locking buckle) are locked and secured when the tailgate is locked against the vehicle body. The tailgate lock adjustment device can sense the amount of snow on the tailgate and adjust the tailgate lock adjustment device accordingly. This means that the tailgate lock adjustment device can effectively overcome the effect of snow on the tailgate opening, ensuring that the tailgate can be effectively unlocked.

[0037] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
